U 87 Ai

From Neumann:

The Neumann U 87 Ai is probably the best-known and most frequently used studio microphone the world over. Its smooth and refined sound is as iconic as its elegant exterior design. The U 87 Ai is the standard microphone for speech and vocals. Three polar patterns plus pad and low cut options make it adaptable to a wide range of applications.

The Neumann U 87 Ai is a true legend. Introduced in 1967, it has shaped the sound of countless hit records for the past 50 years. And when those hits were announced on the radio, many a DJ sat before a U 87 Ai. The legend continues: To this day, no professional recording studio is complete without a Neumann U 87 Ai.

The U 87 Ai is the epitome of a large diaphragm condenser microphone. Its tapered body and iconic headgrille design have become part of the collective consciousness: This is what a studio microphone looks like. The same is true of its sound: The U 87 Ai represents studio quality; it has become the gold standard by which other microphones are measured.
